My invention relates to an iniproveinentin the class of east-nietalerossings (ineluding froefs and more es ieeiall those whieh. or s v -lat least their portions ot nieniherson whieh ..thowheel-tlange groovesinterseet), are east tiaetnring the erossingrs. eirossings they areliahle to heroine ti'aetured of hard metal, and inore. particularlyinanganese steel.

The entire crossing shown in Fig. l Coinprises tour siinilar hollow eastsections A and four similar angular corner-pieces B. llaeh sertion A istorined as a straight hollow radseetion 7 ot the eioss-seetional shapeillustrated in Fig'. t3 and eontaining a longitudinal wheel-flangegroove S and'having 'ohlique t'aees 9 at their ends; and similarguard-rail seetions l() extend outwardly co1'- respondingly ontheopposite ends 'of each rail-section and eontain wheel-flange grooves 8flaring toward their outer ends.

To construct a erossingwith the four Cast sections A. these are.asseinhledby bringing the oblique ends 9 into' meeting contact one withanother. therehy producing the crossing in square torni. as illustratedin Fig. l, heeause each ot' these endsextends at an angle ot'forty-tive, degrees. ,"lhe resultant foi-,mation also hrinfrseorresponding grooves 8 `and S properly into alineinent. It theCrossniflf is to he. say ot rhonihus shape', the angles ot' the ohliqueends should, ot' ieourse, be

.toi-ined to extend aeeordingly. Into .the anl'ular space torinedhetween each of two ad- Jaeent guard-rail seetions 10 tits'a`Correvspondingrly shaped eorner-pieeo B. the sides ot eaeh heine,mextensive with' the r'espec- Before ai'liusting the eornerpuues intoplace, rails Col the traek tor whieh the erossing is pro-' vided areapplied thereto, by titting against the outer t'a-ee ot eaeh guard-railsection the end-portion of a rail and elainping it lietween that taceand the opposingl tace ot the respeetive corner-section. These opposingtaees are shown to he provided with longr tudinallyl extending ribslllto enter the 0pposite sides'olE the rails. the taees ot these rihsheilig i'eeessed at intervals, assliown, to torni protiiheranees llnoi""pads to hear against thel opposite sides ot the weh ot the rail-endeontined hetween them, the rihs also a tlording shoulders conforming to`and titting).r against they opposite iinder'sides ot the rail-head. asrepresented in Fig. 4. lVith the parts asseinhled as deserihed'. angularhraees l2. eontoi-minga lo the inner corners of the erossing. are tiltedinto them hetween the heads and llanges and against the wehs ot` theadjaeent rail-seetion 7. and the asseinhled parts are holted together.as shown.

ty the deserihed seetional eonstruetion ot the erossiue'. thetraelt-rails are not only held niueh more tirinly hv elaniping` eaehliti hetiveen a guard-rail section and the adjacent side ol' acorner-piece l than in the ordinary construction ot crossing, whereinthe parts'corresponding \vith these cornerpieee sides are extended toenahle the endpori'ion ol a rail to he holted to one recessed andtherel'ore \\eal\'ened side ol' the esten sion, but the constructionenahles these ex-v tensions to he wholly omitted with the twol'oldadvantage ot economy ot metal and reducing weight, and the furtheradvantage, by bringing the rails that much closer to the crossing, ofreducing the extent of leverage ol the rails exerted against thecrossing by trains in approaching and clearing it. This leverage alsotends to Ytracture the crossing at and near the iilterseeting grooveswhen the metal has there become crystallized, as it does in time, underthe poundingl ot traversing wheels; and by thus reducing the leverage,the tendency ot its action to fracture the crossing is materiallyreduced.

The, primary object of my invention, nan'iely that of minimizing thetendency to .fracture the crossing hy impact in travers ing it, otwheels passing over the intersections ot the flange-grooves S and 8, `isdue to the yielding of the joints at f), against which the wheelpoundingis directed, sutlieiently to cushion the blows of thepounding wheels,because ot' the separate t'ormation and bolted fastening together of theparts.

I realize that considerable variation is possible in the details ot'construction thus specifically shown and described, and I do not intendhy illustrating a single, specific or preferred embodiment of myinvention to he limited thereto; my intention being in the iollmvingclaims to claim protection upon all the novelty there may he in myinvention as broadly as the state oi" the. art will permit. l

W hat I claim as new and desire to secure by Letters Patent is 1. Arailway-crossing having corner-mem hers formed `with separahly andyieldingly jointed sections having guard-rail sections toi-med thereon,and the joints extending diagonally through the `wheel-Mange grooves attheir ii'ltersections.
